abstract = {This work combines two powerful self-energy techniques: the
well-known GW method and a self-energy recently developed by
us that describes renormalization effects caused by the
scattering of electrons with magnons and Stoner excitations.
This GT self-energy, which is fully k-dependent and contains
infinitely many spin-flip ladder diagrams, was shown to have
a profound impact on the electronic band structure of Fe,
Co, and Ni. In the present work, we refine the method by
combining GT with the GW self-energy. The resulting GWT
spectral functions exhibit strong lifetime effects and
emergent dispersion anomalies. They are in an overall better
agreement with experimental spectra than those obtained with
GW or GT alone, even showing partial improvements over
local-spin-density approximation dynamical mean-field
theory. The performed analysis provides a basis for applying
the GWT technique to a wider class of magnetic materials.},
